Embodiment Construction

[0029] figure 1 Shown are the light emitting semiconductor components 101 and 111 , the encapsulation of the light emitting semiconductor components forming the fluorescence conversion layers 102 and 112 , and the optical damping element 103 . Semiconductor components emit radiation in a defined wavelength range when an electrical voltage is applied. The encapsulation contains a conversion material which emits radiation of a defined wavelength when it is excited by electromagnetic radiation of a defined wavelength range. The conversion material can contain at least one luminescent material. Suitable as phosphors are, for example, phosphors or organic phosphors.

[0030] The wavelength ranges of the excitation and emitted radiation are different. The envelope may either convert all of the radiation incident on it, or it may convert only a part of the incident radiation and pass the rest without significantly affecting the wavelength range of the radiation that is passed.

Abstract

An arrangement having at least two light-emitting semi-conductor components (101, 111) that are disposed adjacent to each other comprises jackets (102, 112), which each at least partially surround the at least two light-emitting semi-conductor components. In the jackets a converter substance is present, which partially or completely converts the wavelength range of the radiation emitted by the semi-conductor components. Between the at least two light-emitting semi-conductor components, at least one optical damping element (103) is disposed, which optically insulates the respective jackets of the semi-conductor components in order to reduce any coupling of at least one jacket (102) into at least one other jacket (112), or in order to reduce the coupling of at least one semi-conductor component (101) into the jacket (112) of at least one of the other semi-conductor components (111).

Description

technical field [0001] The invention relates to a device with at least two light-emitting semiconductor components and a method for producing a device with at least two light-emitting semiconductor components. Background technique [0002] This patent application claims priority from German patent application 10 2007 056 925.6 and German patent application 10 2008 011 153.8, the entire disclosure content of these two German patent applications is hereby incorporated by reference into this patent application. [0003] In order to generate white light with the aid of light-emitting semiconductor components, the light-emitting semiconductor components are equipped with encapsulations containing conversion substances. This conversion substance converts radiation of a first wavelength range (primary radiation) emitted by the semiconductor components into radiation of a second wavelength range (secondary radiation), which differs from the first range. In this way, white light can...
